Equipment Specifications

Component Role: Consumable Chemcassette tape for the SPM Flex — determines which gases the monitor detects. Swap the cassette and select the target gas from the SPM Flex LCD menu
Detection Method / Sensor Type: Chemcassette colorimetric tape
Target Gas/Analyte: Phosgene (COCl2), ethyl chloroformate (ECF) and methyl chloroformate (MCF)
Measurement Range: Phosgene: 2 to 2,000 ppb. Ethyl chloroformate: 0.02 to 30 ppm. Methyl chloroformate: 0.03 to 30 ppm
Relative Humidity Range: Optimum for best accuracy — phosgene 1-95%, ECF 5-90%, MCF 1-95% RH
Response Time: T50 — ECF 6 s at 2 ppm, MCF 10 s at 0.4 ppm, phosgene 15 s at twice TLV
Resolution: Lowest alarm level — phosgene 5 ppb, ECF 0.02 ppm, MCF 0.03 ppm
Additional Features: Sample line particulates filter type A required. Phosgene detection reaches 2 ppb, well below the 100 ppb TLV
Sample Range / Line Length: Maximum sample line 30 m
